Neighbors said the large police presence and taped-off crime scene was an unusual sight on the normally quiet street.

“This is the first time I’ve seen something like this on this street. This block is usually pretty good,” said neighbor Mike Pasquarosa, who has lived on the street for four years. “It’s definitely a shame.”

“This is a quiet street. You don’t really see something like this here,” said neighbor Saul Alicea.

Ward 3 City Councilor Dennis Eaniri, in whose ward the death occurred, said his “heart and concern” went out to the children.

“It always strikes your heart when something like that happens to someone,” said Eaniri. “It’s needless, and there are always children left behind which makes it more difficult.”

On Friday, police were searching for a 2006 gray BMW driven by a Randolph man, reportedly the children’s father, described as a suspect in the case. The vehicle has the license plate 1HFLH0.

Beaulieu is the sixth murder victim in the city this year, five f them since April 11.

Mayor Bill Carpenter was unavailable for comment due to an illness in his family while Police Chief Robert Hayden could not be reached for comment.

Fred Fontaine, the mayor’s director of community relations, would not comment on the woman’s death.
